FIELD: electricity.
SUBSTANCE: device (1) for inductive heating includes: At least three heating coils (10A-10D) installed in longitudinal direction of steel plate (2) so that this steel plate could move inside them; and inductance regulators (L 12 A-12D) which are installed on current conductors (11) connecting each of heating coils with power source supplying voltage on each of heating coils which are made capable to generate self-induction and regulate their own inductance during self-induction, herewith, each of inductance regulators is installed so that mutual self-induction could be generated between at least adjacent regulators.
EFFECT: reducing change of heating speed when steel plate is heated and simultaneous improvement of energy utilisation efficiency.
